- This invention relates to hosiery drying forms and particularly to theprovision in such forms of means for reinforcing, them against internaland external pressure. f

It is an object of the invention to provide a hosiery drying formwithreinforcing means located within the interior of the form and whichfunctions to prevent separation of the side members of the form due tothe pressure of the heating medium within the form. I

A 'further object is to. provide a hosiery drying form withr'einforcingmembers secured to the sides of the form and having portions which areinterengaged or interlocked.

A further object'of the invention is to provide a hosiery drying formwith reinforcing 'means located within the form substantially along itslongitudinal center whereby to increase the resistance to torsionalstrain and thus to prevent separation of the sides of the form at theirjoint.

The present invention finds its utility principally in connection withhosiery drying forms made of sheet metal, such as sheet steel, the formbeing constructed of two sheets cut to shape and welded or otherwisesuitably secured together along their edges. iIt has been found inpractice, particularly with socalled outsize forms, that the forms areapt to swell due to the pressureof the heating medium within the formand there is thus a tendency for the sides to pull apartat' their joint.To prevent this, it has been proposed to construct the form of veryheavy gauge metal which will remain rigid and which will be able towithstand internal pressures but so to construct the form is expensiveand does not offer a certain remedy for this condition. Furthermore,when the form is constructed of very heavy gauge metal considerablegrinding must be done in order to reduce the edges to the necessarydegree of sharpness forcreasing the hosiery boarded on the form.

. It has also been found that forms constructed ofsheet metal are apt tobe dentedduring their construction as for example in-the finishingprocess when the exterior surfaceof the form is subjected totreatmentfor producing thereon a roughened surface or in other operations inwhich the form issubjected to external pressure. j

By the use of our invention, the foregoing disadvantages and defects ofprior construc- A rein-.-

tions are successfully overcome.v forced form according to ourlIlVGIltlOIl' may be made of much lighter metal than has heretofore beenemployed and yet it will successfully withstand external pressure duringthe oflight gauge so that the cost of production of. forms of thischaracter may be in -propor-' tion to those made of less expensivemate-f rials. In accomplishing such purpose the Stainless sheet steel ISince such material is rela tively expensive it is desirable to usestock present inventionis of great value since it overcomes any weaknessin the forms which may'arise from the use of light stocks in theconstruction thereof, its importance increas-J ing the lighter the stockused. Also, being enabled by our invention to construct the form oflighter gauge metal, we can produce a much sharper creasing edge on theform without as much grinding as has theretofore been necessary.

s It has also been found that in forms heretofore constructed there is atendency for the form to whip, that is to say, to bend about a pointnearits base, due to'the fact thatthe form is not sufliciently rigid. Areinforcedform according to our invention isso constructed that the whipis taken out and the form will remain rigid in' upright' position whileitis in use.

Other objects of our invention and additional advantages thereof will inpart be obvious and in part more fully brought out as the description ofthe invention proceeds.

In the accompanying drawings we have illustrated a number of practicalembodi ments of our invention, but it is to be understood that thedrawings are illustrative merely and that theinvention is susceptible ofa wide range of modification without departing from the salient featuresthereof or sacrificing any of its advantages.

In these drawings: c

i Fig. 1 is a view, in side elevation, of a hosiery drying formcontaining reinforcing members according to our invention; I

Fig. 2 is a fragmentary perspective view showing the arrangement of thereinforcing members in the form illustrated in Fig. 1; Fig. 3 is a View,in cross section, of the form illustrated in Fig. 1 showing particularlythe arrangement of the reinforcing members; and

Figs. 4 to 8, inclusive, and 4a to 8a, inclusive, are views in crosssection and perspective, respectively, of modifications of ourinvention, the figures bearing the subscript a being perspective viewsof the reinforcing members disclosed in the correspondingly numberedcross-sectional views.

Referring now to these drawings, the reference numeral 10 indicates,generally, a ho si'er'y drying form of any well known'construction andwhich comprises side members 11 and 12 suitably secured together, as bywelding, at their edges 13 and 14. The form is preferably constructed ofsheet metal, such as sheet steel, the side members 11 and 12 being cutto shape and then welded together by seam welding or other suitableprocess. However, it will be understood that the invention'is notconfined to a form of the particular description above set forth,

I but that on the other hand the invention may be employed in connectionwith forms of quite difierent construction.

In the present instance,'we have shown the form 10 as provided with aseries of reinforcing members 15 which are clearly shown in Figs. 2 and3. These reinforcing members consist of a piece of sheet metal, such assteel, which is bent to form attaching portions 16 and a central. web 17connecting the attaching portions. Preferably, and as shown in Figs. 1and 3, the reinforcing members are arranged in staggered relation on theinterior of the form, the members being secured, as by spot welding,alternately to the sides 11 and 12. By so arranging the reinforcingmembers they overlap, and the loops formed by the webs 17 and the sidesof the form constitute a channel, as clearly shown in Figs. 2 and 3,through which may be inserted a central rib or reinforcing bar 18 whichthen serves the purpose of locking together the reinforcing members and'conse quently, also, the sides 11 and 12.

It will be understood that after the sheets are cut to form the sidemembers 11 and 12, the reinforcing members are secured thereto as, forexample, by welding or other suit able means. Then the sides 11 and 12are brought together and the central rib inserted as shown in Fig. 3whereupon the edges 13 and 14 of the sides 11 and 12 are welded, orotherwise secured together.

Thus, it will be seen that the form described is reinforced by means ofthe members 15 against internal as well as external pressure. It will beclear,-therefore, that the sides 11 and 12 are secured together not onlyat their edges 13 and 14 but, the arrangement of the reinforcing membersand the location of the rib 18 serve to secure the sides together alsoalong their-longitudinal center. Thus, any tendency of the form to bulgedue to the pressure of the heating medium within the form is effectuallyovercome and furthermore any tendency of the form to buckle duringtheprocess of its manufacture is also obviated. For example, in forms ofthe character above described, it is desirable to give the surface ofthe form a finish which shall be sufliciently rough to prevent creepingof stockings boarded on the form. Such a roughened surface may beproduced, for example, by sandblasting under great pressure. 7 Duringsuch process,

the reinforcing members of our invention arranged as herein disclosedefiectually prevent any denting or buckling of the form.

Furthermore, by the use of our invention, the sides 11 and 12 may bemade of a lighter gauge metal than has heretofore been employed inhosiery drying forms with the result that sharper creasing edges 13 and14 may be produced without the great amount of grinding heretoforenecessary. The form, while of lighter metal is adequately supported andreinforced for a substantial part of its length and, as will beparticularly noted from an inspection of Fig. 3, the resistance totorsional strain about the edges 13 and 14 is materially increased byreason of the location of the reinforcing members.

In Fig.4 we have illustrated a modification of our invention. In thisconstruction the form is provided with reinforcing members 19 and 20secured, by any suitable means, to the sides 11 and 12, respectively, ofthe form. By reference to Fig. 4a it will be seen that the reinforcingmember 19 is provided 'with an offset portion 21 which forms a recessfor the reception of a tongue 22 which is cut from and bent outof theplane of the relnforcing member 20. In Fig. 4, the reinforcing mem--bers are shown in assembled relation and it will be clear that in thisembodiment we have also provided reinforcing members which are securedto the sides of the form and which tion the form is also reinforcedalong its lon-v gitudinal center thus preventing separation of the sidemembers 11 and 12 at their edges 13 and ll. The members 19 and 20 form apair of reinforcing members and any desired number of such pairs may beprovided and suitably spaced along the longitudinal center of the form.Inasmuch as the greatest tendency of the form to bulge or buckle is atits Widest portion, that is to say, the portion from the base up toabout the calf, it is unnecessary to provide the reinforcing membersbeyond the last-mentioned point.

A further modification of the invention is disclosed in Fig. 5 in whichthe form is shown to be provided with reinforcing members 23 and 2asuitably secured to the sides 11 and 12, respectively, of the form. Theparticular shape of these reinforcing members is more clearlyillustrated in Fig. 5a and when assembled, as in Fig. 5, it will be'seenthat they have interengaging or interlocking portions 25 and 26,respectively.

In Fig. 6 a still further modification is illustrated and in thisinstance the form is seen to be provided with reinforcing members 27 and28 secured, respectively, to the sides 11 and 12. Each of thesereinforcing members is in the form of an angle and the portions 29 and30 overlap and are secured together by any suitable means, such for eX-ample as a bolt 31.

In Fig. 7 we have illustrated still another modification of theinvention. In this embodiment we have provided reinforcing members 32and 33 which are in a form approximating the shape of a Z bar. Themembers 32 and 33 are shown in perspective in Fig. 7a and in assembledrelation in Fig. 7. As is disclosed in the latter figure the reinforcingmembers have interengaging or interlocking portions 34 and 35,respectively.

In Fig. 8 we have illustrated still another modification of theinvention. This modi fication is substantially like that disclosed inFig. 7 except that the interengaging portions of the reinforcingelements 36 and 37 are substantially of Ushape, as clearly shown in thefigure. It will also be noted that that portion of the reinforcingmembers which is secured to the sides 11 and 12 of the form iscomparatively narrow so that the reinforcing members may be formed inthe same die and may be secured tothe sides of the form irrespective ofvariations in the contour of those sides.

It will be seen from the foregoing description that in all of theembodiments of our invention we have provided a hosiery drying form withreinforcing members secured to the sides of the form and extendinginwardly therefrom. Furthermore, the reinforcing members are arranged inpairs and interengage or are interlocked by. suitable means forexample,.:bythe ribx18 in Fig. 2, the bolt 31 'intFigi 6, and in theother embodimentsby reason of the shapeof the reinforcing members. Byour inventiona hosiery dryingform when made, for example, of sheet metalis adequatelyv reinforced-against pressures from within or Without the'-form, thus rendering the structure rigid under all conditions .of use.Clearly, also, by providing this central support for the sides of-theform, we have overcome the tendency of the sides to separate at theirjointsand thus the form will remain leak proof for a much longer periodthan has heretofore been possible. While reinforcing members of thistype are particularly useful in so-called outsize forms, their utilityis by no means confined thereto, but in fact they may be used in allforms constructed of sheet metal and in every instance they will serveso to reinforce the form that the same may be made of lighter gaugemetal than has heretofore been possible.

We claim:

1. A hollow garment drying form provided with reinforcing membersextending inwardly from its opposing inner surfaces and located whollywithin the form, said reinforcing members being connected togetherindependently of the drying surface of the form.

2. A hollow garment drying form provided with reinforcing membersextending inwardly from its opposing inner surfaces and located whollywithin the form, said reinforcing members having portions whichinterlock with each other.
